 Z represents an oxygen atom or a sulfur atom; 
 Q represents a group represented by formula (II): 
 
       
         
           
           
               
               
           
         
       
       wherein
 * represents bonding position; 
 R 2  represents a hydrogen atom, unsubstituted or substituted C1-6 alkyl group, unsubstituted or substituted C2-6 alkenyl group, unsubstituted or substituted C2-6 alkynyl group, unsubstituted or substituted C1-7 acyl group, or unsubstituted or substituted C1-6 alkoxycarbonyl group; 
 R 3  and R 4  independently represents an unsubstituted C1-6 alkyl group, a C1-6 haloalkyl group, a hydroxy C1-6 alkyl group, a C1-6 alkoxy C1-6 alkyl group, a C2-6 alkenyloxy C1-6 alkyl group, a heteroaryloxy C1-6 alkyl group, a C1-7 acyl group, a C1-7 acyloxy C1-6 alkyl group, a carboxyl group C1-6 alkyl group, a C1-6 alkoxycarbonyl C1-6 alkyl group, a C1-7 acyl amino C1-6 alkyl group, a C1-6 alkyl aminocarbonyl C1-6 alkyl group, a C1-6 alkoxycarbonyl amino C1-6 alkyl group, a C7-11 aralkyl group, a C6-10 aryl carbonyl amino C1-6 alkyl group, unsubstituted or substituted C2-6 alkenyl group, unsubstituted or substituted C2-6 alkynyl group, unsubstituted or substituted C6-10 aryl group, unsubstituted or substituted 5-membered heteroaryl group, or unsubstituted or substituted 6-membered heteroaryl group 
 R 5  represents an unsubstituted or substituted pyridyl group, unsubstituted or substituted pyrazinyl group unsubstituted or substituted pyrimidinyl group unsubstituted or substituted pyridazinyl group, unsubstituted or substituted triazinvl group, unsubstituted or substituted indolyl group, unsubstituted or substituted benzofuryl group, unsubstituted or substituted benzothienyl group, unsubstituted or substituted benzimidazolyl group, unsubstituted or substituted benzoxazolyl group, unsubstituted or substituted benzothiazolyl group, unsubstituted or substituted quinolyl group, unsubstituted or substituted isoquinolyl group, or unsubstituted or substituted quinoxalinyl group. 
 
     
     
       2. The aryloxyacetamide compound or salt thereof according to  claim 1 , wherein Cy represents a phenyl group, R 1b  represents a hydrogen atom. and Q represents a group represented by formula (II). 
     
     
       3. A pesticide comprising at least one selected from the group consisting of the aryloxyacetamide compound and salt thereof defined in  claim 1  as an active ingredient.
